I used a Musical Fidelity LX-LPS before I got an Insight. That Musical Fidelity was pretty nice, but I'm thrilled with the Insight. It is much more quiet, my house seems to have some noise phantoms in it, and the Insight removed them. Exorcized them away. I also wanted to run a Grado woodie low output, and the Insight has most every cartridge out there covered with loading and gain settings.
Even when really pushing the volume, there really isn't any noise behind the music, it's just dead quiet, even at high gain settings. I run a Grado Platinum 3 at 55db of gain, and even when cranking it, it's quiet in the background.
Highly recommended!
